FiiO K17 R2R — FiiO Tears Up the Chip Order

FiiO has spent years building the K-series into the default desktop DAC/amp recommendation, but the K17 R2R is a different animal — it throws out the delta-sigma chip entirely and builds its own resistor ladder instead. That’s a serious, expensive engineering decision for a company that could have just bought another ESS part off the shelf, and it signals FiiO wants to be taken seriously above the price bracket it built its name in.
